These should be loaded from localizedStrings.

Bad localization pattern.
String format itself should be localized, then formatted using translated units
(in C++).

See IDS_DOWNLOAD_TAB_PROGRESS_STATUS and how it is used.

If we end up showing this to user than these should be translated i.e. loaded
from localizedStrings.
